Abstract
The utility model relates to a utensil is assisted to special pull pin of blind round pin in location has solved the problem that the difficulty was extracted to present blind round pin. The technical scheme includes that the device comprises a base, a push rod and an expansion sleeve, wherein a conical expansion sleeve is sleeved on the front section of an inner hole of the base, and the rear section of the inner hole of the base is in threaded connection with the front section of the push rod; the inner hole wall of the expansion sleeve is turned with inverted teeth and is uniformly provided with three grooves along the axial direction; the front end of the push rod is contacted with the rear end of the expansion sleeve, and the rear section of the push rod is provided with an external thread which can be in threaded connection with the pin puller. The utility model discloses simple structure, convenient to use, various blind round pins can be extracted fast to the cooperation pin puller.
Description
Technical field
The utility model relates to machine-building and maintenance field, a kind of specifically shop tool of pulling pin.
Background technology
Alignment pin on existing equipment or the part has two kinds: the last end face of first kind of alignment pin is threaded the hole, and this kind alignment pin can use existing standard pin removal directly it to be extracted, such as often using this alignment pin on the lathe; Second kind of alignment pin is to go up end face not to be threaded the hole, and the bottom outlet of pin is not through hole, is the blind pin in a kind of location (claiming blind pin again).The blind pin in this kind location does not have special-purpose puller, normally utilizes the drill bit earlier boring littler No. one than alignment pin diameter, and end face is attacked standard thread thereon then, utilizes the standard instrument of pulling pin that it is extracted.If but the diameter of the blind pin in this location is very little, then is difficult to the tap out again of holing, be difficult to the problem of extracting thereby exist, so need a kind of being specifically designed to of design to extract the special-purpose accessory that such locatees blind pin.
Summary of the invention
The purpose of this utility model is in order to solve the problems of the technologies described above, to provide a kind of simple in structure, easy to use, the blind pin special use in location that can cooperate pin removal to be used for extracting fast the blind pin in the various location shop tool of pulling pin.
Technical scheme comprises base, also includes push rod and ringfeder, and described base endoporus leading portion is with the ringfeder of taper, and back segment is threaded with the push rod leading portion; Described ringfeder inner hole wall car has sets one's teeth on edge and has groove vertically; The back end in contact of described push rod front end and ringfeder, back segment are provided with the external screw thread that can be threaded with pin removal.
The tapering of described ringfeder is 1: 3-5, its endoporus are cylindricality.
Described push rod stage casing radial section is a polygon.
The radial section of described base is a polygon.
Described ringfeder is evenly opened three grooves vertically.
Described ringfeder is taper, endoporus is a cylindricality, can just in time be inserted in blind pin upper end, location, when ringfeder is pushed when the base leading portion moves, the ringfeder leading portion is held out against by base endoporus leading portion, make ringfeder be subjected to external compression, locate blind pin along the radial contraction locking, setting one's teeth on edge that the hole inwall radially distributes can increase shearing force, described groove is opened one or more at least, preferred three, the ringfeder of three lobes of the formation not only friction during the blind pin of locking is big, and the blind pin in the location after will extracting takes out from ringfeder also and is very easy to.The front end of described push rod establish external screw thread can with the screw-internal thread fit of base endoporus back segment, the rear end of described push rod establish external screw thread can with the screw-internal thread fit of pin removal front end.It is to utilize spanner that screw thread between push rod and the base is tightened for convenience that described push rod stage casing and base radial section are designed to polygon, and makes push rod promotion ringfeder move down preferred hexagon.
Beneficial effect:
1, the utility model is simple in structure, easy to use, can be connected with the pin removal of standard, is used to extract the blind pin in various location.
2, by pushing three lobe ringfeders, ringfeder is radially shunk, utilize the shearing force principle that the blind pin locking in location is extracted, can extract the blind pin in location of all size.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model schematic perspective view.(wherein base is broken away).
1-ringfeder, 1.1-groove, 1.2-set one's teeth on edge, 2-base, 2.1-endoporus, 2.2-internal thread, 3-push rod, 3.1-hex nut, 3.2-external screw thread, 3.3-external screw thread.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further explained explanation:
Referring to Fig. 1, comprise base 2, ringfeder 1 and push rod 3, described base 2 is a hex nut, its endoporus 2.1 leading portions are with the ringfeder 1 of taper, described ringfeder 1 endoporus is a cylindricality, and inner hole wall radially is provided with sets one's teeth on edge 1.2 and evenly have three grooves 1.1 vertically, and groove width is 1mm.Described base 2 endoporus 2.1 back segments are carved with internal thread 2.2, push rod 3 leading portions are carved with external screw thread 3.3, push rod 3 and base 2 are connected by internal and external threads, the back end in contact of the front end of described push rod 3 and ringfeder 1, the stage casing of described push rod 3 is fixed with hex nut 3.1, back segment is carved with external screw thread 3.2, and is corresponding with the internal thread of pin removal leading portion.The aperture of described ringfeder 1 endoporus is slightly larger than the path length of blind pin, gets final product just in time to be inserted in blind pin.
The course of work:
